If, say, you are writing a management agent to run on tens or  
hundreds of thousands of machines so you want the distribution and  
process monitoring more than processing power...

Being able to use Erlang's default distribution model is a major  
benefit. You cannot really do a flat topology, but, frankly, Erlang  
is kinda beautiful for this kind of thing.

Speaking of global (not quotes) -- do you know the mutex algorithm it  
uses for global locks? Is it possible to use global for a subset of  
nodes (based on number you are willing to tolerate failing or the  
number of monitored child nodes a single can support (ie, 50 servers  
coordinating 1000 children each gives you 50k in a very shallow tree)?
